I am having issues with trying to play most .mkv files since the 1.82.0 update . Files that worked before no longer are recognised and mencoder stutters the video and audio. Been having to downgrade to 1.81.0 to watch and periodically change to latest snapshot build to watch larger files using mencoder.Most films now have missing audio , like speech and jump around . To me I had no problems playing most videos before this update and tsmuxer was the number one choice now I cant play anything using it.
